Market Sentiment: General investor optimism or pessimism toward the energy sector and preferred shares affects demand, independent of company specifics. Positive sentiment increases price.

Inflation: High inflation can erode the real value of the fixed distributions from TRP-PD.TO, reducing its appeal, while low inflation makes the yield relatively more attractive.
